ELECTRIC IRON.

To all whom it concern:

Be it known that I, ALBERT VVIoKs, a

subject of the King of Great Britain, re

siding-at Guelph, in the co'unty of \Vellington and Province of Ontario,Canada, have invented certain new anduseful Improvements in ElectricIrons; and I do declare the following to be a full, clean and exactdescription of the invention, such as will whereby the upper 'portion ofthe body of the iron will be prevented from becoming- I heated.

Another object is to; provide. a simple,

- strong and durable iron of this character,

. is a side view. of an electric 1ron constructpended claim.

the parts of which may be easily manufactured and assembled; A furtherobject is to provide an improved construction and arrangement of heatingelement by means of which the electricity. is applied to the lowerpart-of the iron for heatingthe same.

With these and other objects-in view, the invention consists of certainnove features of construction, combination and arrangement of parts asbe more fully described and particularly pointed. out in" the ap- In theaccompanying drawings: Figure 1 ed in accordance with the invention;Fig. '2

of the electric heating element; Fig. 6 is a detail view of the electricheating element" removed fi-om the iron. Fig. 7 isla vertical crosssection on the line 77 of Fig.1.

Referring more particularly to the draw-- ing, 1 denotes the body orbase portion of the iron which may be of any suitable shape and hasformed therein a recess or. cavity 2 corresponding to the shape of thebase 1.' In the toe portionof the base is formed an 'ofl'fset orshoulder 3 having a threaded v Specification of Letters Patent.

' socket the purpose of which Will be hereinafter described. In the rearor heel end of the base is formed a centrally disposed lug 4 which isalso provided with a threaded socket. Arranged in the recess 2 of thebase 1 is a solid iron core or heat retaining 6o element 5, said corehaving a shape corresponding to the shape of the recess 2 and isprovided on its toe end with an overhanging apertured lug 6 which isadapted to engage and rest on the shoulder 3 in the base of the iron,and with said apertufed lug and threaded socket is engaged'a-fasteningscrew I 7 by means'of which the forward end of the core is secured inthe base. In the rear or 7 heel end of the core is also formed a passagethrough which is inserted a fastening screw 8, said screw being engagedwith the threaded socket formed in the lug 4 at the heel end of the ironthus securing this end of the core in place. In the center of the core 5is formed; an upwardly projecting. boss 9 havingformed therein athreaded socket 10.

Arranged on the-base 1 and over-the core 5 is a hollow removable top orupper section 11, the upper side and front portion of which is roundedor curved as shown. In the frontend and. in the opposite sides near therear end of-the base 1 are formed notches 1 with which are engaged lugs11 formed on the upper section whereby the' latter is centered and heldagainst lateral movement. In the curved or rounded upper portion of thetop or upper section is formed a series of vertically disposed passages'or slots .12 and a central longitudinallydisposed .slot

13. The slots 12 are provided to form venti-" lating openings throughwhich they heat of the iron is permitted to eseape,thereby keep ing theupper portion of the iron cool. vThe slot 13 is, provided to receive atongue or rib 14 formed on the lower side of the ban le' attaching shank15 which curves upwar y from the upper portion ofthe iron as shown. Inthe upper end of the shank 15 isscrewed 101 a bolt 16 on which isarranged a handle 17 formed of wood or other suitable material, said,handle being'secured in place by a nut 18 arm. on the oute'r end-of thebolt. .as shown. the rear end of the lower'portion. 10. of the shank.15' is formed a screw hole which alines with the-threaded socket 10 intheboss 9 and through said holein the tongue-is inserted a handle andtop fastening screw 19 which is screwed into engagement with thethreaded socket in theboss 9 thereby securely fastening the handle andupper section of the body of the'iron in place. 3

In the rear or heel end of the core 5 is formed a recess 20 in the upperwall of which is secured the lower ends of combined binding posts andconnecting plugs 21-which are suitablyv insulated from and secured tothe core 5 by clamping nuts 22 and insulated washers 23. To thelower-ends of the posts 21 are connected one end of electric conductingstrips or wires 24 by means of which the posts are electricallyconnected to the electric heating element arranged in the base of theiron. as hereinafter described. The upper ends of the binding posts 2Lproject through an opening 25 formed in the rear end of the top section11 of the iron and are adapted to receive the socket of aflexibleconducting element (not shown) but by means of which electricityis supplied to the heating element of the iron. Above the core 5 andbetween the same and the top of the iron is arranged a filling or layerof asbestos or other non-heat conducting material.

My improved electric heating element comprise's'two bars or'platesformed of mica or similar non-conducting material 26. The

two plates or bars 26 are arranged side by side in parallelrelationbeneath the core 5 and between the same and the bottom of thebase 1 and said bars or plates 26 are wrapped continuously by metalstrips or wires 27, said wrappings forming resistance coils whereby the,current of electricity passing through the same is caused to produce anintense heat. The forward ends of the strips 27 are connected togetherby a suitable clip 28 or said strips may be formed in onecon'tinuouspiece. The. opposite endsof the strips 27 are passed through aperturesformed in the rear end of the plates 26 and are suitably fastened to thelatter. With said rear ends of the strips 27 are connected the innerends of the conducting strips 'or wires 24 the upper ends "of which aresecured to the binding posts 21 asshown. I

Between the upper side of the wrapped bars, forming theheating element,"and the core 5 is arranged a protecting plate 29, and below the heatingelement and between the same and the bottom of the base v1 is arranged aprotecting plate 30. The protecting plates 29 and 30 referred to may beformed of any suitable material but mica is preferably employed. Theopposite edgesof the core- :5,. are insulated from the sides of the baseof the iron by strips 31 of mica or similar non-conducting material,while a similar strip of mica is arranged between the rear of the coreand the adjacent rear end of the base. i

From the foregoing description taken in connection with the accompanyingdrawings; the construction and operation of the invention will bereadily understood without requiring a more'extended explanation.

' Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advan-. tages of the invention as defined in theappended claim. Having thus described my invention, what I claim is:

An electrlc 11'01'1 comprlslng a base having a cavity formed therein, aheat retaining core arranged in the latter, said core having a toe andheel lug each of which is adapted to engage with shoulders forming theend walls of the cavity in the base, fastening de-. vices passingthrough said lugs and into the shoulders for detachably securing thecore to the base, binding posts secure to the core and projectingupwardly therefrom, an electric heatingelement arranged between the baseand the core, saidelement comprising parallel arranged bars ofnon-conducting material, metal strips on said bars to form tworesistance coils in series, electric conducting metallic strips toconnect each end of said heating element with one of said binding posts,means for insulating the heating element from the remaining parts of theiron, a cover sectiondetachabl secured to the base into which the corepro ects, the latter having an upwardly project-ing boss, and, a handlesecured to said. cover and boss, whereby the core is secured to thecover within the longitudinal passage formed therein. i

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

ALBERT WICKS.
